中文摘要	为阐释中国不同农业区的水热资源时空演变格局,利用19612017年全国613个基本气象站平均气温、降水量月值资料,借助趋势分析、Mann-Kendall突变分析、线性回归分析等方法,结合农业区划,对中国及各农业区气温、降水量时空变化特征进行了研究。结果表明:19612017年,中国气温转暖趋势明显,平均增温率为0.249℃/10a,1996年发生增暖突变,同时增温趋势自东南向西北递增,全年增暖在北方最为显著;降水量于2015年发生由减转增的趋势突变,但整体变化趋势并不显著。各农业区气温均表现为显著上升态势,且增温速率北方大于南方、西部大于东部,又以青藏地区增温最为突出,2000年后各区偏暖幅度增大;除黄土高原农业区年降水量有不显著减少趋势外,其余各农业区年降水量呈现增势,尤其20112017年湿化明显。各农业区四季气温、降水量时空分布格局的变化有显著差异,其中青藏高原农业区春、冬季暖干化突出,北方干旱区夏季暖湿化明显,中南、东北地区以夏、秋季减湿为主,东南地区基本存在全年暖干趋势。
英文摘要	In order to explain the regularity of climate change and agricultural climate resources,based on the monthly average temperature and cumulative precipitation data of 613 weather stations in the mainland of China from 1961 to 2017,the spatial and temporal variation characteristics of annual mean temperature and precipitation in each agriculture sub-region were studied by using trend analysis,Mann-Kendall test and linear fitting method.The results showed that,the annual mean temperature over the country showed an increasing trend in the period 19612017,with the increment averaged 0.249℃/10a,an abrupt change air temperature occurred in 1996,and the warming trend increased from southeast to northwest,while the highest appeared in north;the abrupt change of precipitation with the pattern shifting from decrease to increase occurred in 2015,while the linear trend of annual precipitation did not change obviously;for each agricultural sub-region,the temperature presented an obvious increasing tendency with the amplitude in northern and western greater than southern and eastern,respectively,and the most prominent one is the Tibetan Plateau;precipitation showed varying degrees of increase in each agricultural sub-region,except the Loess Plateau,and it was getting wet for the whole study area in the period from 2011 to 2017;the spatial and temporal distribution patterns of temperature and precipitation in four seasons are significantly different,agricultural area of the Tibet Plateau turned warm and dry in spring and winter,arid region of north china became warm and wet in summer,south-central and northeast became dry in summer and autumn,while southeastern existed warm-dry trend throughout the year.
